Video playback problem (not that it's slow). Garbled screen.

So it seems that I'm unable to play back any video format besides WMV.
WMV's play back fine while other formats (e.g. xvid, divx) do not play back at all. Coreplayer crashes to today screen or shows me a green garbled screen with vertical lines.
WMP just freezes and does nothing.
Is this a known issue (I didn't find anything using search)?
Any format of audio plays back perfectly fine (as long as it is not embedded in a video).

I had this, you need to change the Video driver to Raw frame buffer and all will be well. I use TCPMP and this was what I had to do for it to work.

I had done this at first initially too, but simdeo (fellow member) suggested Imageon setting, but NOT Imageon Hardware decoder. This has massively improved speed and visual quality, but you will get intermittent lines across the interface, but not in full screen mode. Settings should be:
TCPMP:
Video Driver = ATI IMAGEON
Buffering = Microdrive (ticked)
Advanced = Tick only: D-Pad, Use System Vol, Benchmark (none od these settings affect performance, just my preference - but selecting other options may adversly affect performance)
Direct Draw = YV12 and tick 'Overlay with colorkey' only.
That's it. Best performance to date and can play torrent or own DVD rips perfectly, providing they were not encoded as high as 640x480.

I'm having the same problems but cannot for the life of me find any settings on Coreplayer that will let me change the buffer settings or the driver.
I'm sure I'm missing something here.
Coreplayer version =1.0.4 build 716
It's the latest version afaik.

Ok, I found the settings in Coreplayer (yeah, I know, should have looked harder..) and all is now well.

Ok, so I've got really decent playback from standard 350mb XVid TV programs but I'm still having what appear to be buffering problems.
Does anyone know what the ideal buffer settings are?

I have found that overclocking the CPU yields in much better playback (although not perfect).
If I want to view a 640x480 video I run the CPU at 728 Mhz (what program would allow higher?), but still the fps is not up to par. I would say the playback is around 90-95%.

Hi Calavaro. What app are you using to o/c the CPU? & exactly what settings do you use? Oh and lastly what's the power consumtion like if left on 728 Mhz all the time?
Cheers.

we use PHM to overclock our device, if you set to 728 and push mail and bluetooth all the time, you won't last for whole day, maybe just about 7 hours. But really you don't need your device on 728 all the time, and personally i think 728 is a bit unstable, so i use 662 when my device is on, otherwise 228 the rest of the time to save battery.
You MUST disable the internal scale from the PHM setting, otherwise it won't work

just wanted to say thanks for this thread. was going nuts with the same problem re: vertical lines, pink screen, etc. almost made a post to ask you guys what kind of parameters or settings you used for your video players. i use core and i confirm that the "raw frame buffer" works well.
cheers

About TCPMP with the best settings applied as mentioned in this thread, is there something else we can do to further improve the playback quality?
I have some clips that feature "fast moving action" e.g. action scenes in movies. These clips will actually play, but when the "fast moving action" is there, you can see that it isn't going really that smooth/fast enough, resulting in noticeable, fast upcoming blocks/lines when you look closely. I'm not sure how to describe this effect best, but I guess pretty much everyone knows what I mean here.
Thanks!!

Hi.
Try playing any 3 minute segment of the video you have then click on File/Media Info and check the resolution of your video. If its below 640x480, then the problem is most likely a low bit rate used to encode the video, hence the pixelated blocks in high speed.
You can get away with less, but I encode now only at 480x320 @850kbps and get superb results each time...DVD quality and High definition quality too when I encode from HD source.
Can't say anymore than that. Click on my name and look through my posts, there will be a recent one entitled something like 'Excellent playback via Coreplayer & TCPMP'. This should help a bit if you have the time to read.

audio video sync

Hi guys loving my Ameo, had it 5 Weeks now, read all the posts about video problems, I have a great picture with tcpmp, the only trouble about 5 minutes into a video and the audio video goes way out of sync, I have tryed everything with tcpmp, no luck am i missing somthing, anybody got the same problems.

I have the same problem with Windows Media play WMV's, the longer i watch the vid the more out of sync it seems to gets, normally the audio comes after the video, and the time just keeps increasing. then when i press pause. the video stops instantly and the audio carries on until it catches up.
However, if i plug the advantage in to the power surpply it doesn't seem to be as bad. It makes me think that it is due to the CPU speed, mentioned in http://forum.xda-developers.com/showthread.php?t=305214
But if anyone has any ideas about how to keep it in sync it would be appricated.

ive tried it with the power cable plugged in. still losing sync. just stopping and starting it corrects sync problem. i have now tried a number of rips. all converted in different formats. resolutions and bit rates still lose sync. anybody got any ideas

same problem here..anybody who knows how to solve this problem?

which version of TCPMP are you using?

doesnt matter which i use,even with coreplayer it goes out of sync
this problem i did not have with mda pro

im affraid this is all to do with the ati chipset and tcpmp, until a fix is found this is going to happen. the best i can get is about 4 minutes. and ive tried most variations in frame size, rate, and bit rate, even files which play at 120% still lose sync.

i went back to watching movies on my psp partly because of this and also as the picture quality is much better as well!

Strange. I use TCPMP to watch all the films and TV shows I download from torrents, and they all play fine. I've never had any problems with the sound going out of sync.

I also never have any out of sync problem. This device rocks for video playback, by my standard. I do lots of youtube and downloaded movies, and the picture is really really good with TCPMP.

I converted a dvd movie to avi 1400MB(high settings) and with this video i have no out of sync.Very strange is with 700mb divx xvid movies its going out of sync.

I've the sync problem too in coreplayer and tcpmp.

is it not possible to get codecs to add to pocket media player so it will play divx etc? As far as i know media player supports the graphics chip so performance should be better

if it was possible , someone would have done it woudnt they?
this problem is one of the major sucky things about this device

Posting to an old post, I know, but as I'm also having the audio/video sync problems, I thought I'd ask everybody that DOESN'T have the problem if they'd be so kind as to specify their EXACT settings.
In my case I'm using Core player.
Under Video I'm using ATI Imageon, Video quality = High, Smooth zoom = on, Dither = ticked and Accelaration = unticked (I have problems with it ticked)
Under Advanced I've even ticked Override AVI timing based on Audio, but no difference. I've also changed the A/V offset to -0.45 seconds, as per another post relating to this issue, with no result.
Under buffering my normal buffer size is 4192, set to preload at 70% underrun, with preload for audio set at 65 KB.
I've ticked Microdrive mode. with the buffer size being 16000 KB and the starting point being 1472 KB

WMP & Coreplayer on X1

Hi,
Got my Xperia X1 the other day, I have got Coreplayer Mobile as well as the WMP on the phone. I have copied the videos I took with my Nokia N95 to the memory card Ive got in the Xperia.
However when it comes to playing them WMP will play them but it stutters alot with the sound being ahead of the video. In coreplayer there is no video only sound.
Any of you guys got any suggestions to get the video playing smoothly. The videos are .mp4.
Thanks

Try to set in Videosettings QTv Display, here I get a picture and it works ok, not the promissed 30 fps but arount 20 fps with a HDTV Movie.

Then I don't have any more ideas. Perhaps it'll help trying TCMP instead of Coreplayer?!

Found this on Coreplayers website:
CE/Windows Mobile/PocketPC/Smartphone

Is anyone running Coreplayer? Is there anything better?

I've tried to find a resolution/bitrate which gives me smooth video without stuttering and dropouts. I've tested on CorePlayer with DivX and native mp4 codecs.
With a resolution of 400x240, 25fps, 1100kBit/s I get a picture without dropouts and a benchmark around 105%.
If I go higher in resolution I start getting dropouts.
I've set the CorePlayer to Microdrive mode and doubled the size of the buffer to increase the speed when reading from the memory card.
I've tried to copy the clip to the phone memory, but with the above settings I see no difference.
My conclusion is that if you want a smooth picture, don't go above the mentioned resolution. It won't give you that crisp picture, but I get more annoyed when the film is stuttering than getting a HD resolution on a 3" display.
I have no problem seeing mp4 on the CorePlayer though. But if I uncheck the "TyTN II driver mode" in QTv Display settings, I get only sound, no picture, despite the MSM7200 chipset . Don't know if the Nokia's format differs from the one I have used (Cucusoft Ultimate DVD).
Is there anyone else who manages getting a higher picture quality without any dropped frames?

Got this from the Coreplayer forums:
'We are on the verge of the v1.3 bug fix release that addresses many of the current issues including those diamond users running WM 6.1...... however it does not address the QTV issues since there is nothing we can control there other then to express our dismay to both HTC and Qualcomm for not opening up the GPU.
Hey... we've been here before.... lets hope for a more open solution soon enough.'
I wonder what SE's position is on this? Apparently it's meant to have a decent GPU but what's the use if we can't use it? I know one or two people here have contacts with SE - anybody wish to find out?

Praying for hardware supported video playback...

but they said that X1 uses ATI GPU not Qualcomm!
Another lies from SE?

Hey guys, i know this is abit off topic, but has any of you guys had the problem were you install core player, then play a video, and then you exit and go back into it and you the the message "cannot validate the serial number/user ID"? i have uninstalled and reinstalled heaps of times, tried different serial numbers, but it happens all the time use it once, and then the message comes up when you go back into it.

Why do you have multiple serial numbers?
Surely it's one Serial per IMEI?

Says who, I haven't seen any info about it, any links please.
Of course the qualcomm chip has indeed 3D hardware acceleration but I don't know if it is ATI.

unbelieveable how unprofessional are they! 1st the RAM debate, and now this; not to mention that bad launching and availability.

It is rather disappointing. Even the fish panel is hardly super smooth, leading me to wonder if even that uses the GPU acceleration.
I really do hope SE allow and encourage developers to tap the GPU of the X1 otherwise its little better than all the other WM phones.
I have hope that someone with a reputation like SE will see the sense supporting the developers. The "write something for the panel" is not good enough. The radio is a panel and as the panel is like the home screen, anything on it is turned off when I navigate away from it including the radio.
I really do hope they do not turn out to be as bad as networks like T-Mobile which can't be bothered to support HTC rebranded phones even if its got their name stuck on them.

after using it for 3 days it is now clear that the panels just use low res screenshots and no live data. They dont even update them, i live in germany and when accessing panels the screenshot says New York etc until it finally updates.
So for the panels just being low res screenshots (that must be only some KBs per panel) the performance is horrible and laggy. Cant believe they use any form of hardware acceleration for that either.

If the video is encoded in H.264 it's going to be lagging full on. Half of the frame will get dropped. Playing 720x400 24FPS at 1Mbps encoded with XviD on the other hand is smooth and not a single frame is dropped. I've tested this with TP.

Does anyone know how to change the default streaming video player to Coreplayer?
It's very annoying when browsing and the Streaming Player kicks in rather than Coreplayer. I've associated 3gp, mpeg4, etc. with CP but doesn't seem to make any difference.

Audio and video out of sync.

Does anyone have issues with video playback? It seems that every file I throw at the hero seems to have audio and video synchronization issues. Specifically, video lags behind audio, you hear something and see it later. I've tried HTC's player and Meridian. The files play on my pc just fine and aren't huge files.
Are there some recommended bitrates for Hero? I'm using an iPod/phone converter (videora) to get my files encoded which has options for bitrate. Bit disappointed that the Hero can't keep up with iPhone again though.
EDIT: Good News, scroll down for my conversion settings.

Hi, there are multiple threads on this subject on this forum. Just open the Hero main forum:
http://forum.xda-developers.com/forumdisplay.php?f=508
... and do a search for "video" from the "Search this forum" -tool to the right.
In short, the Hero has massive problems playing mp4-video without a glitch. The best I've acchieved is smooth video that slows down a bit and then becomes faster to catch up with the timeline every 10 seconds.
This can be done by using an exact set of conversion options with one of many many encoders. Some say it works perfectly for them, but I suspect their eyes are just not as finely tuned as mine
Main thing seems to be the target resolution can be no higher than 480x360.

Try encoding/downloading psp video files its not 100% but very close

Cheers dude, I did look but I can't find anything about synchronisation, my videos aren't dropping frames (or at least that doesn't bother me), it's just that the audio is constantly out of sync with video. Makes everything look like it's dubbed, when people talk their lips don't match the sound. You see an explosion (for example)and hear it later.
I'm going to do some experiments with bitrates and converters today.
How exciting!

4 hours later, 3 different converters and no good news.
Has anyone got any settings and a converter to recommend?

Dude try using psp settings. I was having the same issues with avi's & mp4's but now I'm using psp settings its almost perfect

Could you post what the settings are? I tried a load of things earlier and it was all rubbish.
Resolution, bit rate for video and audio as well as file type would be grrrrreat!

Well, I -THINK- I've cracked it.
There are some dropped frames still but image quality is good and the sound is in sync. Here are the settings when using Handbrake http://handbrake.fr/?article=download to do the conversion:
If I don't give a value for it, then you don't need to change it.
Format: MP4
Crop: Automatic
Width/Height: 480 / Blank
Anamorphic: None
VideoCodec: Mpeg-4 (FFmpeg)
Framerate 23.976
2 pass encoding: Check
Avg Bitrate: 750
Audio Source: Automatic
Audio Codec: AAC
Mixdown: Stereo
Samplerate: 48k
Bitrate: 128
That's the best result I got after HOURS of experimenting but I'd be interested if anyone has anything better.

I see you already went ahead and did your own tests... Here are some relevant threads:
http://forum.xda-developers.com/showthread.php?t=544498
http://forum.xda-developers.com/showthread.php?t=550529&
I myself, haven't been able to get Handbrake working with any settings. Audio always stutters like crazy, so the video is basically unwatchable.
What does work for me is Videora, which has a bunch of free converters bundled for a specific platform, so you can get a Videora iPod -edition and a Videora HTC-edition. There's a general edition as well.
The GUI is horrific and loads weird web pages into a huge box inside the program (presumably to allow advertising whilst using the program), but I did manage to get the smoothest playback out of it of all the converters I tried. I think I even went with default settings for HTC G1-video.
The video plays ok, the sound and video are in sync, but the video slows down and catches up every 10 seconds or so.
Hope you get it working! I am pretty hopeful that the coming update will alleviate the problem...

Thanks, will have a look at those threads. The Videora converter didn't work well at all for me, I'm wondering if there are certain files that retain characteristics that the phone doesn't like. IE that you may get a better result with converting from divx to mp4 than, for example high quality mp4 to something the hero can handle.

Coreplayer 1.3.6 Judder - stock ROM 1.48 (SOLVED)

I've done a search and read many posts about coreplayer performance on the HD2. Most have no problems but some do and i'm one of them.
I have no problem playing the files using these settings from member Shasarak (thanks mate):
Options/Video and activate Dither, then "smooth zoom always" rather than "smooth zoom 50%". You will get substantially better performance if you then go into the DirectDraw settings page, choose "YUY2" as your overlay format, leave "use device stretching" checked, and uncheck the other two boxes.
I have tried all other settings and combinations but i agree the above gives the best performance.
However, i am still experiencing occassional judder and it's annoying me.
1). would upgrading to stock ROM 1.66 make a difference?
2). is there ANYTHING else i can do to stop the judder? i've already tried disabling background tasks, wifi etc
3). The audio is also very slightly out of sync, it's delayed, it's minor but i notice it. It happens on all videos, they are all .avi I've not seen anyone complain of this before.
Thanks

With regards to uadio sync:
Menu --> Tools --> Settings
Select the 'Advanced' page
Manual A/V offset let's you adjust the audio sync

The judder is most likely due to the format the videos are encoded in just eating too much CPU. How do you encode them?

I don't encode them, just downloaded movies in the common divx/xvid format. I played movies on my old N96but re-encoded them to mp4 as it didn't play avi and i never tried coreplayer on it.
Perhaps i should try re-encoding, but don't see why this phone couldn't handle a standard 700mb divx avi.

cheers mate, you are the man! putting a -0.300 has made it much better, not sure why it would be out like that on all movies? I'm very happy with that What do the other 2 settings do - soft drop tolerance & hard drop tolerance?
now just to fix the juddering.
I've found, and i think someone else suggested this in another thread, that if you pause it for a moment it sorts itself out. Would rather not have to do that but i don't see a way around it

The standard ~1h30 700MB divx movies I've tried to play all worked nicely. But sorter ones of the same size (meaning more bitrate) could start being too much load. Just try and do a benchmark in coreplayer with a video that causes problems, if you have less than about 150% average playing speed you might start getting drops.

It may help to put the phone in "Airplane Mode"; if it's checking for email messages in the background while playing it will judder like crazy. Use the task manager to kill off any other running applications as well....

I come to the conclusion that this phone just can not handle playing divx/xvid in avi very well, and i'm not sure why it can't.
I have gone back to my old ways of converting the video to mp4 using winavi mp4 converter, this also cures the problem of any files that have ac3 audio as it converts that as well.
On my 8 year old computer it would take 30 mins to convert a 700mb film, i have since bought a quad core Dell running 64 bit windows 7 and it converts in less than 10 mins!!
Smooth as butter now but a shame i have to go back to doing this. But at least the files will play in coreplayer, windows media and htc's player so plenty of choice
If anyone wants the settings i use for winavi mp4 converter then just ask away. It's not free but mine was if you get what i mean
EDIT:
I HAVE FOUND THE REAL PROBLEM, IT'S MY COREPLAYER! IT STARTED STUTTERING THE MP4 FILE THIS MORNING, WHEN I SWITCHED TO WINDOWS MEDIA OR HTC PLAYER IT WAS FINE 9OBVIOUSLY COULDN'T DO THIS BEFORE AS NEITHER OF THOSE PLAYERS SUPPORT AVI)
I JUST TRIED COREPLAYER AGAIN AND IT'S PLAYINNG THE SAME MP4 FILE FINE NOW, MUST BE SOMETHING WRONG WITH MY COREPLAYER, WILL GET ANOTHER VERSION.
WHAT A DRAMA AND SORRY FOR BORING YOU ALL WITH IT LOL
